It's also a technique museums use: https://australianmuseum.net.au/how-do-i-prevent-insects-damaging-my-artworks

I had a cabinet that showed signs of furniture borers. Pedestal and backbox were a minor hassle to find a freezer big enough:

I used a 3 seat "wrap and move" sofa cover for the main cabinet, some duct tape and a vacuum cleaner to get most of the air out:

That cabinet will fit in a 500L chest freezer that a friend on a farm has. Just have to empty the entire frozen (butchered) cow out first, put the cabinet in and then stack all the frozen meat back inside. Few weeks later, reverse the process and leave it wrapped while it thaws.

The Australian Museum recommends freezing for 7 days minimum: https://australianmuseum.net.au/how-do-i-prevent-insects-damaging-my-artworks
